They're not sisters like me and Kakak, but they have a strong relationship. It's more than sisterhood, I can tell. From one of their posts, they said they once live together under one roof. As for me and my sister, never expect us two to do that. Walaupun kita tinggal serumah, tapi kami berlainan atap. Kakak tinggal di main house sama Mumski dan Papa, sedangkan DocCii bersama dua adik laki-laki kamarnya di bungalow. Kalau kita seatap... bisa ancur kacau balau rumah kami :D
